Aetiology

Authoring team

The aetiology of patellar tendon rupture may vary according to the age:

  • in younger patients - usually caused by significant trauma or cumulative microtrauma
  • in older patients - often associated with degenerative changes associated with aging (1)

The following factors have been implicated as contributors for rupture of the tendon:

  • injury - laceration and direct blows
  • chronic diseases
  • local Corticosteroid Injections
  • complication of knee surgery - total knee arthroplasty, a late complication of a tibial nail, removal of the central third of the tendon for anterior cruciate ligament (ACL)
